Universal centrifugal pump wear ring test bed

Abstract

The invention discloses a universal centrifugal pump wear ring test bed comprising a wear ring test unit, a fluid medium supply unit, a leaking liquid collection unit and a test table. The fluid medium supply unit, the wear ring test unit and the leaking liquid collection unit are installed on the test table. The fluid medium supply unit communicates with an inlet of a seal cavity of the wear ring test unit. An outlet of the seal cavity of the wear ring test unit communicates with the leaking liquid collection unit through a pipeline. The universal centrifugal pump wear ring test bed has the beneficial effects that the universal centrifugal pump wear ring test bed can be suitable for measuring leaking amounts of wear rings of different wear ring gaps, different wear ring lengths and different wear ring types; and operation is quite convenient, only the test wear rings need to be replaced when experiments are done on different samples, and most structures do not need to be detached. Measurement results are accurate, the medium leakage amounts are accurately measured through complete sealing of a rotor part and the difference method, the experiment precision is greatly improved, and reliability of the results is ensured.

Description

technical field [0001] The invention relates to a universal centrifugal pump port ring test bench, in particular to a general test bench for studying the influence of various parameters of the centrifugal pump port ring on fluid leakage. Background technique [0002] Centrifugal pumps are widely used in the transportation of fluid media in industry and life. Improving the working efficiency of centrifugal pumps is of great significance for energy saving and emission reduction, as well as reducing the production cost of enterprises. There are mainly three kinds of losses in the operation of centrifugal pumps: mechanical loss, volume loss and hydraulic loss, and the leakage loss of the mouth ring is an important part of the volume loss. The leakage loss of the mouth ring refers to the sealing ring at the impeller inlet, that is, the mouth ring. There is a pressure difference on both sides. The pressure on one side is close to the outlet pressure, and the pressure on the other ...
